GUN-MOUNTING.

SPECIFICATION forming of Letters Patent No. 508,278, dated November 7,1893.

' Application filed February 28, 1893. .Serial No. 4631390. (No model.) Patented in England January 21, 1890, No. 1.078,and in France June 8, 1889, No. 198,814, and February 26, 1890, No. 204,021.

To all whom it may concern:

Be it known that I, JEAN BAPTIsTE GUS- TAVE ADOLPHE CANET, engineer, a citizen of the Republic of France, and a resident of Paris, France, have invented certain new and useful Improvements in or Relating t o Gun- Mountings, (for which I have obtained patents in Great Britain, No. 1,078, dated January 21,1890, and in France June 8, 1889, No. 198,814 and No. 204,021, dated February 26, 1890; French patent of addition, February 8, 1892, to No. 204,021, dated February 26, 1890; French certificate of addition, dated Decemher 14, 1889, to Patent No. 198,814, dated June 8, 1889,) ef which the following is a specification, reference being had t0 the accompanying drawings.

This invention'relates to gun-mountings.

and comprises an improved construction of chassis, brake cylinder, base-plate, and platform, and mode of mounting the carriage on the platform, also improved means for traversing the gun, and turning the carriage or chassis on the platform, and combinations of these parts as hereinafter described.

An important object of the present invention is to provide for the rapid horizontal adjustment of the chassis vwhereby the gun can be placed for example parallel with the side of the ship or battery and there secured.

The mounting is so constructed that the gun when trained or traversed turns about an imaginary vertical axis outside the mounting and preferably passing through a point 'in the port-hole or embrasure in the side of the vessel or wall of the battery. The mounting is also constructed to permit the easy recoil of the gun, and the securing of the gun in any desired position.

Referring to the accompanying drawings, Figure 1 is a side elevation of the gun and mounting, the latter being shown partly in section. Fig. 2 is a sectional plan showing the chassisI in two diierent positions. Fig. 3 is a side elevation of the gun and a portion of the mounting removed from the chassis. Fig. 4 is a rear view of the parts shown in Fig. 3. Fig. 5 is a section on the line was, Fig. 3. Fig. 6 is a longitudinal vertical central section of the parts of the mounting shown in Fig. 3, the construction of the rear sleeve being slightly modified as hereinafter described. Fig; 7 is a horizontal section on the line y y Fig. 6. Fig. 8 is a transverse section on the line .e e Fig. 6, and Fig. 9 is a plan of the air-recuperator, and section of a modied construction of brake cylinder hereinafter described'.

Like letters denote corresponding parts throughout the drawings.

A is the gun.

B, B are forward and rear sleeves through which the gun can freely slide; C, C are side frames or beams connecting said sleeves; C C are the trunnions formed on said side frames; D is the carriage in which the trunnions are supported.

E is a platform on which the carriage rests;

and F is an arc shaped base plate formed with racer. paths on which the platform can travel.

Upon the gun is secured a hoop or ring G i I in halves and held by means of a ring g2 in a recess g3 formedin the gun. The said projections g form an interrupted collar on the gun, into the interruptions 9 of which project and lit parts of the hoop or ring G. By

this means the gun is prevented from turning in the said hoop or ring G during the firing. The hoop G is formed with grooved guides G', Figs. 4 and 5, which slide on the side beams C, C during the 'recoil and running out of the gun. b b, Fig. 3, are stops carried by the for- Ward sleeve B and intended to limit the outward run of the gun by encountering suitable buers b b on the hoop G. The brake cylinder H is secured to or formed with the. hoop G beneath the same and carries the recuperator springs 1I, I. I sometimes use a com-h pressed air recuperater in lieu of the springs I, I. The piston rod H of the brake cylinder is passed through and secured to the rear sleeve B either direct-ly as shown in Figs. 6 and 7 or indirectly by`m`eans of a bush h which is screwed in the said sleeve as shown in Fig. 1. The latter mode of attachment allows of the dismounting of the piston from the rear without necessitating the. complete IOO disinouuting of the sleeve B. By arranging the brake cylinder below the gun as described, the width between the cheeks of the carriage may be reduced to a minimum.

The brake may be of any suitable type such as one having a cock or valve for controlling the flow of the liquid; the one shown in Figs. 3 to S is furnished with a taper rod H2 secured to the cylinder end and arranged to enter a central aperture inthe piston for the purpose of regulating in a well known manner the area of the opening in the piston through which the liquid displaced by the entrance into the cylinder of the piston rod H flows from one to the other side of the piston during the recoil. The liquid so displaced operates to force outward the movable head H3 of the brake cylinder and thereby compresses the spring recuperator which serves to run out the gun at the end of the recoil. The head Irl3 is suitably packed to prevent leakage of liquid. The recuperator spring I, I, I', I are threaded upon rods J. The springs I', I bear at their forward ends against the front of a piece H0 which bears upon the movable head H3 and at their rear ends against nuts J screwed on the rods J. The springs I, I bear at their rear ends against a flange Il4 of the brake cylinder and at their forward ends against shoulders J2 formed on the rods J. J3 is a piece secured to the brake cylinder and forming a guide for the forward ends of the rods J.

In the brake apparatus shown in Fig. 9 the forward end of the brake cylinder is extended to form a second cylinder which is fitted with a tightly packed piston K and which communicates through pipe with a compressed air recuperator L fixed beneath the gun. The end of the brake cylinder proper is pierced with an axial opening H5 and is formed with a tubular extension Il6 which projects into the hollow piston rod Il. The forward end of the said axial opening l-l5 is adapted to be closed by a non-retu rn valve I-l7 which is loadedv with a light spring. The rear end cover of the cylinder is in this construction fixed to the cylinder., Vhen the recoil takes place, the liquid displaced by the piston rod ll passes along Ythe tube Il, raises the valve Il?, enters the second or extended cylinder and displaces the piston K therein, thus compressing still more the air in the recuperator L with which the forward face of the said piston is in contact. For running the gun out again the liquid is allowed under the pressure of the air in the recuperator acting on the piston K to return into the brake cylinder proper through a by-pass Il8 which is iitted with a screw down-valve Il whereby the area of the opening and consequently the speed of running out can be regulated.

'lhe chassis or carriage l) is capable of turning about avertical axis on the movable platform E which is supported by conical rollers resting upon arc-shaped racer paths provided on the base plate F. The platform E is supported at three points only and is therefore evenly supported in all positions, notwithstanding that there may exist unevenness in the track or racer paths. I prefer to support the platform on a system of ve conical rollers. One roller M is situated at the front of the platform and rolls on an inner racer path or track F and the other four rollers N are situated at the back and roll on an outer racer path or track F2. The said rear rollers are arranged in pairs, each pair being pivoted in a triangular' frame O whichV is connected to the platform at O. The said frame O is capable of oscillating about the center O and thus allows the rollers N to accommodate themselves to the unevenness of the track if such exist. By this construction the advantages of supporting the platform at three points only are combined with a distribution of the load on the track over more than three points.

The base plate F may be made in one, two, or more parts provided with the aforesaid inner and outer curved racer paths F', F2 which have their centers outside the mounting, for example in the port hole or embrasure of the ship or battery, so that when the gun is trained horizontally the chase of the gun does not move laterally to any material extent, and consequently the width of the said port hole or embrasure need not be much greater than the external diameter of the chase of the gun. P, P, are claws secured to the platform, and which engage a rim formed on the base plate to prevent the lifting of the platform during firing.

The means for training or traversing the gun are as follows: A curved rack Q having teeth Qshown in full lines, Fig. Land in dotted lines Fig. 2, and struck from the same center as the racer paths is fixed in the base plate, and with this rack is geared a pinion Q fixed on a vertical shaft Q2 which is carried by the carriage or chassis D. The said shaft passes axially through a hub D formed on the carriage which hub has a bearing in the platform and forms the axis about which the carriage can turn with respect to the platform. On 'the upper end of the shaft Q2 is fixed a worm wheel Q3 which gears with a worm Q4 having its bearings on the carriage. The worm can be driven by a hand wheel l, Fig. l, acting through a shaft lt', gear wheels R2, chain wheels R3, R", and chain lt connecting said wheels. Bolts S, Fig. 2, are provided for locking the carriage D to the platform inval-ions positions. lVhen it is desired to turn the gun away from the firing position and secure it for example in a position parallel with the side of the vessel or battery, the platform is first moved, by turning the hand wheel R, to any position wherein 1t can be secured to the base plate, as for cxample at the extreme ends of its travel. 'lhen the platform is locked to the base plate by suitable clamps, and then the bolts which lock the carriage to the platform are raised or removed so as to unlock the carriage. ,lf now the hand wheel R b.e again rotated then, since .the platform is locked, the shat't Q2 cannot turn, and therefore the worm Q4l must travel round the Worm Wheel Q3, and the carriage will therefore be turned on the platform. and can thus be brought to any desired position and there secured either by the bolts S or by other means.
